To all whom it may concern:

Be it known that I, EDWARD K. ROBINSON, a citizen of the United States,residing at Belmont, in the county of Middlesexand State ofMassachusetts, have invented certain new and useful Improvements inBookbinding or Book-Covers, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to the binding of books, pamphlets, catalogues, orother similar material in such a manner that-the cover or binder ispermanently attached to the initial contents (whether it be book,pamphlet, or catalogue, etc), but permits of the inclusion of additionalmaterial-a pamphlet, a notebook, blank leaves, or any other similarmaterialin the form of a supple-' ment to the initial contents withinthe Same.

cover or binder The purpose of my invention is to make it possible toplace additional material of Such nature inside of the same covers andwith the original contents of a book, without breaking or tearing thebinding. With the extra leaves or a pamphlet placed within the coverswill ordinarily cause the binding to weaken and break.

In the accompanying drawings, Figure 1 is an end view of a book bound inthe manner herein described, before the insertion of any supplementalmatter. Fig. 2 represents a book similarly bound, to which a supplementhas been added. Fig. .3 is another View of a book bound according to myinvention, to which a supplement has been added. Figs. 4 and 5 showbooks bound in accordance with my invention, to which the supplementshave been attached by means of cords or wires. 6 is a detail illustrat--ing one mode of attachment of the permanent part of the book to thecover.

In the figures, a represents the leaves of the book, bound" together bysewing or by any of the methods commonly used by bookbinders, andattached to the back strip 1) either'by being glued to the whole surfaceI of the back strip 6 or by means of a strip of cloth a attached to theleaves and also glued to the side covers, 0 and d. In Fig. 6 thepermanent contents of the book are shown attached to the cover in bothof these manners, each of which is well known to bookbinders. The coverfor the book, in cluding the sides and the'back, may be one or morepieces of cloth, leather, or other material suitable for covering books.It

will preferably (but not necessarily) be reinforced withboard or otherstiff material to form the sides of the book, 0, (Z.

The length of the back of the cover from the point e to the point fwhere it is attached to the side (Z, is sufficient to permit of the attachment of the original contents to the cover and to providein additiona strip 9, wh ch may be of any desired breadth. This strip g forms aportion of the side of the cover in the original binding of the book,but when it is desired to place additional material within the covers itmay easily be bent back so that it becomes a part of the back of thebook, as represented in Fig. 2, wherein it represents the pamphlet orextra leaves that have been added.

It will be observed that I have represented the side of the cover, (Z,as projecting slightly more beyond the leaves of the book as originallybound, than the side 0. By this arrangement the projections 2', j, ofthe covers beyond the ends of the leaves, will be more nearly equal whenthe Supplement has been added. These sides 0 and d may however, be madeof the same length or (Z may be made longer than 0, if such arrangementis preferred in any particular case.

The supplementary matter it may e attached to the cover (Z, to the back(7, or to the end paper In of the original contents, or to any or all'of them, by any suitable device. Such attachment can be made by gluingor pasting to the cover (Z, the back 9,

the original cover d of the book,'and in this pocket has been insertedthe cover m of the supplement h. The supplement may be attached also byrunning a cord, wire, or other similar material between the middleleaves of it and around the back g, and securing or tying it firmlytohold the contents h in place. Such attachment can also be made byinserting eyelets in the back strip and passing a cord through the.eyelets and through the leaves of the supplement.

Fig. 4 shows a book bound according to my invention, to which asupplement has been added, said supplement being attached by a cord 91.running -between the middle leaves of the supplement and around the backof the book. Fig. 5 illustrates a book bound according to my invention,to which a supplement has been added, the supplement being attached by acord a passing through eyelets o inserted in the back strip, and throughthe leaves of the supplement. Likewise, holes may be punched through theside of the book and fasteners inserted corresponding places in thesupplement h.

through them and through holes punched in The attachment maybe made invarious other ways without departing from my invention.

The arrangement of the book cover herein described may be applied toboth sides of a book; that is, the side 0, can be made like the side 01,which would permit the addition of extra material at both the front andthe back of the book.

:What I claim as new, and desire to secure by Letters Patent'is:

1. A permanently bound book having the permanent contents thereofattached to both of the side covers, a back for the permanent contentsof the book, and a strip of material connected flexibly to the back andone side cover, said strip'being adapted to serve normally as a part ofthe side cover, and when a supplement is added to the book, as a backfor such supplement.

2. A permanently bound book having a back to which the permanentcontents of the book are bound, and side covers,-one of which isconnected to the back by a strip of material adapted to serve as part ofthe side cover until a supplementis added to the book and then to serveas a back for such supplement.

In testimony whereof, I have hereunto subscribed my name this 22d day ofJune, 1911.

EDWARD K. ROBINSON.
